[jira] [Commented] (TIKA-1351) Parser implementations should accept null content handlers

["Tyler Palsulich (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TIKA-1351?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14372099#comment-14372099 ] 

Tyler Palsulich commented on TIKA-1351:
---------------------------------------

I think this would be a nice feature. But, it's a large task to update every Parser. I believe there is a DummyContentHandler which just discards everything (but extraction is still done)? I forget the name.

> Applications which want to let users search documents based only on their metadata do not need to get the content parsed. 
> The only workaround I've found so far is to pass a no op content handler which can ignore the content events but it does not stop the parser such as PDFParser from parsing the content.
> Proposal: update parser API docs to let implementers know ContentHandler can be null and update the shipped implementations to parse the metadata only if ContentHandler is null
